To all whom it concern:

Be it known that Gnonon A. SEIB, citizen of the United States, and resident of lllion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

My invention relates to typewriting machines, and more particularly to the type actions thereof. 7

In typewriting machines wherein the pivoted type bars are mounted in a segmentally arranged series, it has been found difficult to provide sufficient room in which to mount the requisite number of type bars and yet provide sufficient room between them in the basket, so that in operation conflict between adjacent bars may be avoided. This is particularly true where the type bars of the entire system are of uniform length and are mounted side by side with their pivotal centers in a single are or plane, as for example where the type bars are mounted in guideslots of a segment to turn on a single pivot wire with all arts of the latter disposed in the same p ane.

The main object of the present invention is to provide a simple and efficient construction by which these difiiculties may be overcome and which is eas to manufacture.

A further object o the invention is to enable the features of m invention to be incorporated in existing orms of typewriting machines without material modification thereof and without modifying the appearance of the machine.

To the above and. other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of arts and combinations of devices set fort in the following specification and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views,

Figure 1 is a fragmentary fore and aft vertical sectional view of a typewriting machine embodying my invention.

Figure 2 is a detail fragmentary front elevation of a portion of the same.

Figures 3 and 4 are detail fragmentary plan views, partly in section, and showing two left-hand and two right-hand type bars, respectivel I have sliown' my invention in the present instance embodied in an Improved #10 Remington machine in which the invention may be incorporated with but slight modification of the machine as it now exists. It should be understood, however, that the invention is not restricted to its embodiment in such machines, but may be employed in illustrated only so much of the machine as may be necessary to arrive at an understanding: of the invention.

he frame of the machine comprises a base 1, corner posts 2, and a top over which the carriage (not shown) travels from side to side of the machine and carries a platen 4. Segmentally arranged upwardly and rearwardl striking sheet metal type bars 5 of uni orm length are mounted at theirheels in guide slots 6 in a. t e bar segment 7 on a pivot wire 8 carrie by the segment. The arc-shaped pivot wire is disposed in an upright plane, and all parts thereof are arranged at a, uniform distance from the, int of convergence 9 of the ty e bars. From an inspection of Fig. 2, it will be seen that the distance between adjacent slots in the segment gradually increases from the center to the sides of the system.

plate 3,.

Each type bar moves from its seental the base 1 of the machine, and is pivoted at 16 to the associated sub-lever 14. Each sub-lever is pivoted on a pivot wire 17 carried by a cross bar 18 fixed to the base of the machine. The upper end of each sub-lever carries a headed pin 19 which entersa slot 20 in the heel of the companion type bar. A segmental universal bar 21 supported for backward and forward movements on the segment is actuated by con-= tacts 22 on theztype bars. A rearward movement of the universal bar 21 transmits movement through arms 23 on said universal bar to arms 24 on a rock shaft 25, and from a centrally disposed arm 26 on the rock shaft to a link 27 to actuate the can riagc cscapement, as disclosed in the patent to Oscar Woodward, #1342489 dated June 8, 1920.

The parts as they are thus far described are the same asthose employed in the Improved #10 Remington machine. In said machine, however, the guide slots in the type bar segment are all cut in radial planes which correspond to the radial planes of movement of the body portions of the type bars, all of said planes radiating from a common point of convergence of the type bars, which is the center of the are defined by the pivot wire 8.

In accordance with my invention, as it is disclosed in the present instance, I propose to maintain the gradually increased spacing of the slots from the center to the sides of the system, but to cut all of the guide slots 6 in planes that converge at a single off-set point 28 on the median plane as of the segment. This point is nearer the pivotal centers of the type bars than the center 9 of the are defined by the pivot wire 8. The plane of movement of theheel of each type bar. or that portion thereof received in its guide slot 6, is coincident with the plane of its slot; the planes of movement of all of the heels converging at the single point 28. On the other hand the body portion of each type bar is bent laterally upwardly or outwardly of the plane of its slot. The result of this is that 1 the body portion of each of said bars will not move in the plane of movement of its heel, but in a different plane and in printing position all of the type bars will converge at a common center 9 corresponding to the center of the arc defined by the pivot wire 8, and the laterally bent body portions of the type bars will fan upwardly when at rest in the basket, as will hereinafter more clearly appear.

In carrying out my invention in the present instance, and in accordance with the specific showing of its embodiment disclosed herein, it is intended that all of the fortytwo type bars shall be mounted in oil-set or off-centered slots as specified, although only a few of the type bars are illustrated to simplify the drawings.

In Fig. 2 the dotted lines 29 indicate planes converging at the center 9 of the segment,

or the center of the arc defined by the pivot wire 8; each line cutting through its slot 6, whereas the dot and dash lines 30 indicate the planes of the off-set or ofi-centered slots 6. It will be observed that the planes 30 converge at a single point 28 off-set inwardly from the center of the segment, or off-set towards the pivot wire 8 from the center 9 of the arc defined by said ivot wire. By comparison of the two sets 0 lines 29 and 30, the extentof oil-setting in the present arrangement of the planes of the'slots 6 from the true radial planes of the segment may be readily observed.

After each type bar is mounted in place in its guide slot 6, it is bent laterally and outwardly or upwardly of the plane of said slot; the oint of the bend being indicated at 31 in ig. 2 and the line 32 crossing all of the type bars where such bends 31 occur. By this arrangement the body portions of the bars when in printingposition converge at a common point 9, and all are properly received in the type bar guide 12 and strike at a common printing center 11. As each type bar returns to and remains in a state of rest in the basket. it assumes a different and higher position from what it would if mounted in a radial slot on a line 29 in the ordinary manner, as clearly indicated in the drawings. Instead of the body portion of each bar extending'in a straight line fore and aft of the machine when at rest, the bars are slightly fanned in opposite directions from the center to the sides of the system, so that each type bar remains deflected slightly away from its adjacent bar, as indicated in Figs. 3 and 4. The type carrying ends of the terminal bars are therefore at a higher elevation in the basket than they would be if mounted in radial slots on the lines 29. This is clearly indicated at the left-hand side of Fig. 2 and in Figs. 3 and 4. It follows that more room is provided in the type rest for the system of type bars, and that a greater space is provided between each pair of adjacent bars to avoid the liability of conflict between them in their movements towards and from the type rest and at points adjacent thereto.

From the foregoing, it will be understood that in the construction as shown and described in the present instance, each type bar 5 may be said to comprise a heel or pivot end portion 33 included between the bend 31 and the rear end of the bar; a shank or body portion 34: between the bends 31 and 35, and a stem 36 from the bend 35 to the free end of the bar and on which stem the type block 37 is mounted, It will be seen, moreover, that the stem 36 is bent laterally at an angle to the body portion or shank 34. and that there is a slight lateral bend at 31 between said shank and the pivot end portion 33, so that each portion 33, 34 and 36 lies in a difierent plane and each shank 34 swings to single unvarying center and effect a cutting of the slots with greater speed and facility and with less liability of inaccuracy than.

in my former construction, thereby greatly facilitating the manufacture of the product. Various changes may be made without departing from my invention.

What I claim as new and desire to secure by Letters Patent is 1. In a typewriting machine, a system of segmentally arranged pivoted type bars movable at their heels in converging planes, the point of convergence of such planes being on the median plane of the system and intermediate the pivots of the type bars and the point where the bars converge in'the printing position.

2. In a typewriting machine, a system of pivoted type bars each having its heel moving in one plane and the body ortion thereof in another plane, the planes 0 movement of the heels of all of the type bars converging at a single point on the median plane of the system and intermediate the pivots of the type bars and the point where the body portions thereof converge in the printing position.

3. In a typewriting machine, a system of type bars, and a slotted segment having its bearing slots converging at a common point on the median plane of the segment and 011'- set inwardly from the center of the segment and in which slots the heels of the type bars are pivotally mounted, the body portion of each type bar being bent outwardly from the plane of movement of its heel and from the plane of the companion slot in which it it mounted so that the type bars when in printing position converge at the center of the segment. 1

4. In a typewritin machine, a system of segmentally arrange pivoted type bars of uniform length, the heels of the type bars moving in planes which converge at a point on the median plane of the system off-set inwardly from the center of the arc in Which the pivotal centers of the type bars are situated, the body portion of each bar being bent outwardly from the plane of movement of its heel so that the type bars in the printing position all converge at the center of said arc.

5. In a typewriting machine, a system of type bars of uniform length, a slotted type bar segment carrying an arc-sha ed wire on which said type bars are pivote the planes of the bearing slots in the segment in which the heels of the type bars are mounted converging ata common point on the median plane of the segment oif-setinwardly from the center of the arc defined by said pivot wire, the body portion of each bar being bent laterally from the plane of movement of its heel so that the type bars in printing position converge at the center of the arc defined by the pivot wire.

6. In a typewriting machine a system of segmentally arranged pivoted type bars a pluralit of such bars at one side of the system aving their heels moving in planes that converge at a'single point in the median plane of the system below the point where the. type bars intersect when, in the printing position.
